Affiliate Marketing Secrets

Does anyone have any information about this site? I have been a long time aol email user, and today when I went to send an email, it said that there is an error and that I must complete the image challenge at challenge.aol.com/spam. I have never ever had this issue before, and am wondering if this is some sort of scam/method to obtain my account information, as this site requires a username and password. Does anyone know if this is really from aol/affiliated with it, and has any information? Thank you
